Make sure you wear clothes that are comfy as possible. People that have eczema have skin that is very sensitive to certain fabrics. Try sticking with clothing made of breathable fabrics like cotton or cotton blends. Try to avoid wearing synthetic fabrics or wool since these materials can cause flare-ups.
Use an antibiotic ointment on severely cracked skin. This can prevent infections from forming. It also serves as a moisturizer. Do this sparingly though; prolonged use of antibiotic ointments can render them ineffective. If you do have an infection, you should consult your doctor, who may give you an oral antibiotic.
